Custom Visualizations in Power BI and their use
Many times Visualizations are used to effectively present one’s data and are the basic building blocks of any Business Intelligence tool. Power BI entails various default data visualization components which include simple bar charts to pie charts to maps, and also complex models including waterfalls, funnels, gauges, and many other aspects.
With the help of Power BI, one can create a visualization in two ways. First is by adding from the proper side pane to Report Canvas. By default, this is the table type visualization that is selected in Power BI. The second way is to drag the fields from the right sidebar onto the axis and value axis under Visualization. Here, you can add multiple fields to each axis as per the requirement.
In Power BI, it is also probable to move one’s visualization on the reporting canvas by simply clicking and then dragging it. Here a user can switch between different types of charts and visualizations given from the Visualization pane. Power BI thus attempts to convert the selected fields to the new desired visual type as identically as possible.
Adding a custom visual to Power BI reports
Yes, Custom visuals are often added to Power BI reports by many methods, either by downloading .pbiviz files from Microsoft AppSource or through the integrated Office Store of custom visuals in Power BI Desktop. Utilizing AppSource requires the additional step of downloading the file.
Although, AppSource provides a link to download a sample Power BI report (.pbix file) in order to learn how the visualizations are used, such as how it uses field inputs and formatting options. Additionally, AppSource entails a short video tutorial on building report visualizations with the custom visual.
The search bar is located at the top and the vertical scrollbar on the right which can be utilized to browse and identify custom visuals in order to download. Each custom visual tile in AppSource includes a catch on now link which, if clicked, presents the choice to download either the custom visual itself (.pbiviz file) or the sample report for the custom visual (.pbix file). Clicking anywhere else in the tile other than Get it now prompts a window with a detailed overview of the visual, a video tutorial, and customer reviews.
If a custom visual (.pbiviz file) has been downloaded from AppSource, the Import from file option can be used to import this custom visual to the report. Additionally, both the Import from store and Import from file options are available as icons on the Home tab of the Report view in Power BI Desktop.
Unlike AppSource, the visuals are assigned to categories such as KPIs, Maps, and Advanced Analytics, thus implementing it easy to browse and compare related visuals. More importantly, utilizing the integrated Custom Visuals store further avoids the need to manage .pbiviz files. It also enabled report authors to remain focused on report development.
